The hook entry was an absolute /home/kuhy/utils path, copied from a config
written for ~/.claude where it only ever ran locally. On an Actions runner
that is exit code 127 — "No such file or directory" — so gatelock-precommit
and crdt-sync-precommit failed on every commit of this refactor while the
hook silently checked nothing. Now repo-relative, matching the sibling hooks
(`entry: scripts/check_subproject_scope.sh`): pre-commit always runs from the
git root, so it resolves the same in both places.
Fixing that made the CI configs runnable locally, and `--all-files` then found
what per-file runs had missed — ruff pruning imports that exist *for* their
re-export. `import crdt_sync` was broken three separate ways (FileSyncStateStore,
encode_key, FileCredentialStore). Each affected module now states an explicit
__all__ so the autofixer cannot take them again, and the two files that pushed
past the cap once __all__ was added are split further:
_firebase.py 260 -> 247 + _fberrors 25
_sync.py 257 -> 188 + _syncargs 91
Test patch targets followed the code they patch: gatelock._outputs.shutil ->
_xrandr.shutil, gatelock._arbiter.Path -> _claims.Path.
gatelock and crdt-sync both pass `pre-commit run --all-files` in full;
389 and 259 tests at 100% branch coverage; the root gate exits 0.

Cut at concern boundaries, not line counts: test_sync_skips.py holds the five
cases where a peer's pushed file is missing, corrupt, wrong-shaped or our own
— one story about what sync_log declines to merge — rather than an arbitrary
half of the original class.
259 passed at 100% branch coverage, verified against a clean HEAD worktree.
